Embodiment 1

[0033] Embodiment 1 of the present invention provides a pixel driving structure, for details, please refer to Figure 5 , Image 6 The schematic structural diagram of the pixel driving structure shown, the pixel driving structure includes M data lines and N scanning lines, and the M data lines are vertically arranged in columns and parallel to each other (such as Figure 5~Figure 6 D shown 1 、D 2 、D 3 ,...,D M-1 、D M ), the N scanning lines are arranged horizontally and parallel to each other (such as Figure 5~Figure 6 G shown 1 , G 2 , G 3 , G 4 , G 5 , G 6 ,...,G N-1 , G N ), the M and N are positive integers, where:

[0034] The M data lines intersect with the N scan lines to form a plurality of pixel units arranged in a matrix, wherein each pixel unit includes at least any two sub-pixels among the four sub-pixels of R, G, B, and W , for example: each pixel unit may include two sub-pixels R and G, or two sub-pixels R and B, or two sub-pixels R and W, or two ...

Embodiment 2

[0063] Embodiment 2 of the present invention provides a display device, which includes the pixel driving structure described in Embodiment 1.

[0064] Specifically, the display device can be any product or component with a display function such as a liquid crystal panel, an electronic paper, an OLED panel, a mobile phone, a tablet computer, a television set, a monitor, a notebook computer, a monitor, a notebook computer, a digital photo frame, a navigator, etc. .

Embodiment 3

[0066] Embodiment 3 of the present invention provides a driving method of the pixel driving structure described in Embodiment 1, the method comprising:

[0067] When displaying a frame of pixel images, a signal greater than the reference voltage (voltage deflection polarity is "+") is input to one of any two adjacent data lines among the M data lines, and the other The data line inputs a signal lower than the reference voltage (voltage deflection polarity is "-"), and the M is a positive integer.

[0068] It should be noted that, for the same data line, when displaying any two adjacent frames of pixel images, the input voltage on the data line will be greater than the reference voltage (the voltage deflection polarity is "+") and less than The reference voltage (the polarity of the voltage deflection is "-") is changed, and it is not fixed.

[0069] When the driving method described in the second embodiment of the present invention is used to drive the pixel driving structure...

Abstract

The invention discloses a pixel driving structure, a driving method and a display device. The structure comprises a plurality of pixel units which are formed by crossing a plurality of data wires and scanning wires and are in matrix arrangement, wherein each pixel unit respectively at least comprises two sub pixels. By aiming at a connecting unit formed by the pixel unit of any one uneven row in each line of pixel unit and the adjacent subsequent pixel unit in the even row, the sub pixels in the uneven digits and the sub pixels in the even digits in the connecting unit are respectively connected with one of two data wires used for controlling the connecting unit, in addition, the sub pixels in any one uneven digit and the sub pixels in any one even digit in the connecting unit are connected with any one of the scanning wires of the connecting unit, and the scanning wires connected with the sub pixels in any two uneven digits or any two event digits in the connecting unit are respectively different. In the pixel driving structure disclosed by the invention, the use number of the data wires is reduced, in addition, the Z reverse rotation can be realized, and low cost and low power consumption are realized.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal panel pixel driving structure, a driving method thereof, and a display device. Background technique [0002] With the continuous development of liquid crystal display technology, liquid crystal display (Liquid Crystal Display, LCD), which has the advantages of small size, low power consumption, and no radiation, has gradually replaced cathode ray tube (Cathode Ray Tube, CRT) display as the display device. Mainstream products are increasingly widely used in various electronic products. [0003] Such as figure 1 As shown, it is a schematic diagram of a pixel driving structure of a traditional TFT (Thin Film Transistor, Thin Film Field Effect Transistor) LCD in the prior art. The pixel driving structure includes M data lines (Data Line, also called Source Line), N Scanning lines (Gate Lines, which may also be referred to as gate lines), wherein the ...
